On Friday, Samsung complained to US trade authorities about Osram and two of its subsidiaries and launched a countersuit for alleged patent infringement by Osram against Sansung. Fellow Korean LED maker LG launched a similar legal action.
The moves follow legal action by Osram on 6 June against both Samsung and LG for alleged infringement of its LED patents on both thermal management and blue-to-white light conversion. The companies deny the infringement.
Samsung said it ‘intends to vigorously enforce its intellectual property rights, and these lawsuits reflect Samsung LED’s commitment to that enforcement’, the company said in a statement.
Osram said it was ‘well prepared’ for the actions taken by Samsung.
‘Our objective in taking legal actions against Samsung and LG group companies is to prevent unauthorized use of our valuable technology,’ Osram LED chief Aldo Kamper told the Press. ‘We have a considerable number of patents which we developed in the course of many years of intensive research and development work. Major competitors such as Philips, Cree, and Nichia have acknowledged our strong IP position by entering into cross-license agreements with us’.
The patent row accentuates the rivalry over the growing LED lighting market between the traditional lamp makers and the so-called Asian invasion of electronics firms.
